J/AJ/119/2866       Proper motions of metal-poor stars      (Beers+, 2000)

Kinematics of metal-poor stars in the Galaxy. II. Proper motions for a large non-kinematically selected sample. Beers T.C., Chiba M., Yoshii Y., Platais I., Hanson R.B., Fuchs B., Rossi S. <Astron. J. 119, 2866 (2000)> =2000AJ....119.2866B
ADC_Keywords: Stars, metal-deficient ; Positional data ; Radial velocities ; Abundances ; Proper motions Keywords: Galaxy: abundances - Galaxy: halo - Galaxy: kinematics and dynamics - stars: Population II - surveys Abstract: We present a revised catalog of 2106 Galactic stars, selected without kinematic bias and with available radial velocities, distance estimates, and metal abundances in the range -4.0≤[Fe/H]≤0.0. This update of the 1995 Beers & Sommer-Larsen catalog (Cat. J/ApJS/96/175) includes newly derived homogeneous photometric distance estimates, revised radial velocities for a number of stars with recently obtained high-resolution spectra, and refined metallicities for stars originally identified in the HK objective-prism survey (which account for nearly half of the catalog) based on a recent recalibration. A subset of 1258 stars in this catalog have available proper motions based on measurements obtained with the Hipparcos astrometry satellite or taken from the updated Astrographic Catalogue (second epoch positions from either the Hubble Space Telescope Guide Star Catalog or the Tycho Catalogue), the Yale/San Juan Southern Proper Motion Catalog 2.0, and the Lick Northern Proper Motion Catalog. Our present catalog includes 388 RR Lyrae variables (182 of which are newly added), 38 variables of other types, and 1680 nonvariables, with distances in the range 0.1 to 40kpc. File Summary:
